General Discussionaccounts found exploiting

hopefully Valve will do something about it as well

Good work indeed. That "report player" link is such a great idea.

How were they actually exploiting?

Queuing against themselves using VM's or multiple PC's in a school or home network in solo queue.

Go mid vs yourself, feed yourself, team leaves, keep your feeder online and feed team to up your stats.
